ORE-WASHING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 239,204, dated March 22, 1881.

Application filed December 30, 1880. (No model.)

To all whom it may concern:

Be it known that I, JAMES H. TOTMAN, of Plattsburg, in the county of Clinton and State of New'York, have invented a new and Improved Ore-Washing Apparatus, of which the followingis a specification.

The object of this invention is to provide a a simple and effective device for keeping the journal bearings in ore-jigs and other machines free from dust, sand, and other substances that otherwise get in them and cut the journals and bearings.

The invention consists of a double ring or annular box closed at the bottom and open at the top of the annular space between its sides, and having a lateral opening from said space for the introduction of water therein. It being designed to set said water-box about a journal or journal-bearin g and to force a constant stream of water through the lateral opening, so that said water shall flow out of the annular space in the box against the journal or bearing, and thereby keep 0E all dust, sand, &c., which might otherwise lodge on or in the same.

In the drawings the water-box is shown applied to thelower journal-bearing of an ore-jig.

Figure 1 is a sectional side elevation of an ore-jig with the water-box applied. Fig. 2 is a plan of the water-box in position, with part broken away to exhibit other parts.

Similar letters of reference indicate corresponding parts. In the drawings, A represents the jig-tub, designed to be nearly filled with water, and provided with a cross-timber, A, to support the journal-box of the jig discharge-pipe.

B represents the jig suspended on a vertical shaft, B, and submerged in the water of the tub A for about one-half its depth.

(3 represents the central vertical dischargepipeot' the jig B, revolving in a journal-box, O, that is fixed in the cross-timber A. Down through the pipe 0 all the refuse sand and other substances pass into the spout D, that is arranged beneath the opening of said pipe 0, and through said spout D the refuse is delivered outside of the tub A.

E represents'an elevator running on a shaft, E, designed for elevating the concentrated or washed ore from the tub A.

A portion of the fine ore and sand falling through the perforations in thejug B into the water of the tub A always gets into thejournal-bearings that are in the water--the bearings of the jig discharge-pipe and of the ele vator-shaftand soon cuts them out, often in a few hours work, thereby causing great loss of time, expense, andtrouble. In order to prevent this efl'ect of the fine ore and sand, I apply a water-box, F, about the dischargepipe 0, above its journal-bearing G, as shown, and attach to the water-box F a water-pipe, Gr, through which water is constantly forced into said box F and out of its ann ular chamber f against the said discharge-pipe (J, thereby keeping all ore, sand, &c., away from said pipe 0 and its bearing. Said water-box F has the top of its annular chamber f drawn in, as shown at g, from the outside, whereby the water introduced through the pipe G and lateral orifice h of said box F is directed to a common center, as indicated by the arrows, Fig. 1. This water-box may also be applied to the elevatorshaft E with equally good effect. Hence it will be seen with a simple and inexpensive device important economies in time, labor, and cost are assured;

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- The combination, with a jig-tub, A, jig B, suspended on shaft B, and discharge-pipe 0, of the water-box F, having its top drawn in to the shaft, and provided with holes whereby the water from a supply-rape, G, is thrown upon the shaft above its bearing and the sand washed ofi" before it can enter said bearin g, as described.
